I've just installed 128MB SIMM in my RPC, and I'm now getting a buzz on
sound when the HD is operating, or some mouse operations performed. Does
it matter which slot it goes in? I had two memory cards before, and put
this single one in the slot nearest to the back, the other being now
empty. A !SICK check shows everything tickety-boo.

I'm not sure if it's the number 128, or the type of memory installed, but
mine does that as well - although not all the time. I also have 128MB (2 x
64MB) but I do seem to remember it happening with less. It isn't
intrusive, but I suppose that depends upon your sound system and whether
or not you are editing audio at the time.
I just thought it was a VIDC 'thing' or bus loading.

A single SIMM can be fitted in either socket.

SICK wont tell you if you have used RAM with unsuitable electrical qualities
though.
Its normally for there to be some analogue pickup of bus traffic on an RPC,
it should not be not excessive at normal volume levels. Beware of using
amplified speakers with automatic gain, as these will greatly ramp un the
sensitivity to pick up even a tiny amount of hum, unless a sound is output to
set the level to something sensible.

My old series 1 motherboard with 16bit sound and mixer boards were much
more prone to this than my present series 3 one, however it could be
reduced by changing the routing of the internal cables particularly the
sound cable from the CD drive and the flying lead from the board. Perhaps
when the RAM was changed the cables were moved.

That's helpful and easily checked - it's quite possible I've routed it
differently from before in this rather densely packed RPC. ;-)
